West Ham United boss Sam Allardyce has no idea what Louis van Gaal's claimed 'philosophy' at Manchester United is. Allardyce wrote in the London Evening Standard: "United have only lost once since November 2 which I find quite surprising considering the amount of criticism they have received, especially directed at their defence.
"In spite of that they are only three points better off than at this stage last season under David Moyes.
"Louis van Gaal has talked about his philosophy but I'm struggling to see exactly what it is because he changes things nearly every week.
"Sometimes it's a back four, other times it's a three, sometimes it changes at half-time.
"It can be a diamond, 4-3-3, 4-4-1-1 - he's tinkering but in fairness, it seems to be working."
